Hello William,

Thank you for reaching out. Could you please attach your model file too? That would help us test and debug on our end. Thank you.

Sincere regards,
Parth

Hello, Parth
This is my model.
the xTaskCreate( " ", ) function running time is undercontrol or not ?

Hi William,

The xTaskCreate Stack Depth seems to be sufficient.

The problem seems to be due to the very high sample time (0.001) that has been set View

Please change it back to "auto" and try again View

Let me know how it goes.

Sincere regards,
Parth
